| Studies on phytoplankton community diversity cannot be limited microphytoplankton (cells>20 ìm), it is indeed necessary to take into account also the nano (3-20ìm) picophytoplankton (<3 ìm) components. In the frame of this work aimed at studying temporal phytoplankton community diversity two complementary methodologies of phytoplankton sample analysis, pigment and genetic (metarbarcoding) diversity, have been used as alternative to routine morphological analysis carried out at light microscopy. The REPHY station (047-P-016 Concarneau Large) off-shore the Concarneau Bay has been sampled during the annual highest phytoplankton production (March-July 2012) with a frequent sample interval strategy (twice per week). Results obtained by both pigment and... |
